WALL CONSTRUCTION.

Specification of Letters Patent.

Patented July lll, lmlt.

Application filed April 3, 1916. Serial No. 88,708.

To all whom it may concern:

Be it known that we, CLARENCE W. Lone and JOSEPH W. STEPHENS, citizensof the United States, residin at Dallas, in the county of Dallas andtate of Texas, have invented certain new and useful Improvements in WallConstruction, of which the following is a specification.

This invention pertains to new and useful improvements in wallconstruction.

The invention contemplates the erection of a wall formed of superimposedparallel tiers or slabs spaced apart to give the wall the desiredthickness; while transverse partition connect the slabs and are soarranged as to form vertical columns into which concrete is pouredwhereby vertical studs are produced at desired intervals as well asvertical air spaces between the studs. Such a wall when completed andfinished has the nature of a monolithic hollow wall.

Broadly stated walls of this character have been built and certainpatents granted thereon; however in the course ofevolution certainimprovements have been developed and our invention relates particularlyto these improvements.

In carrying out the invention a slab of plastic material is provided andformed near each end with a vertical groove on its inner face while itsouter face has longitudinal grooves formingseats for the finishingmaterial with which the outer side of the wall is coated. The ends ofthe slabs are provided with vertical grooves and theslabs are made intwo lengths.

In forming the wall the slabs are built up in parallel tiers spacedapart and transverse tie plates formed with vertical ribs or tongues attheir ends connect the tiers, the plates extending between adjacentslabs and the tongues being seated in the end grooves of the slabs. Theslabs are placed in staggered relation so that the plates of one coursewill be under the vertical grooves of the superposed course and theplates of said latter course will be over the grooves of the firstcourse. Partition plates inserted between the slabs and engaged in thevertical grooves will cofiperate with the tie plate in producingvertical columns in spaced order and which may be filled with concretewhereby studs are produced.

The vertical grooves are provided near each end of the slab in order tomake the same interchangeable and reversible and it is to be understoodthat only one groove of the slab is used. In forming a corner the slabsare permitted to project, their ends being connected by the tie platesand a suitable form is set up so that a concrete corner column or postmay be formed and the slabs and plates locked into the same.

Considerable difliculty has been experi enced in walls of this characterin providing rounds or means for nailing or fastening ase boards,frames, moldings and the like on said walls. Owing to the thinness ofthe slabs they cannot be plugged successfully. In overcoming thisdifliculty we provide wooden blocks which are used in connection withthe shorter slabs and are interposed in the desired course between theends of the slabs so as to be co-incident with the studs which provide asubstantial back of a wall. construc ed in accordance with theinvention,

Fig. 2 is a vertical sectional view of a similar wall,

Fig. 3 is a detail of one of the slabs,

Fig. 4 is a detail of one of the shorter slabs,

Fig. 5 is a detail of the tie plate,

Fig. 6 is a detail of the partition, and

Fig. 7 is a detail of the wooden block.

In the drawings the numeral 1 designates a plastic slab preferablyformed of a mixture of cement and sand as is common in this art. Theslab is provided at each end with a vertical groove 2 while on its innerside it has a pair of vertical grooves 3, one located near each end. Onthe outer face of the slab a pair of longitudinal grooves or seats 4 areformed and when the slabs are laced in the wall these grooves aline andorm channels in which the finishing material or mortar will seat, thusobviating the use of lathing or false-work.

Tie plates 5 provided near their ends on CWT each side with verticalribs or tongues 6 are versely and interposed between the adjacent llllends of slabs, the tongues 6 engaging in the grooves 2, in tongue andgroove relation, whereby the slabs at one end of the plate are tied tothose at the other end of the plate and held against lateraldisplacement. The slabs are laid up in 'two tiers or planes spaced apartand tied together by the plates.

Plastic partitions 7 have their ends 8 reduced to fit the verticalgrooves?) of the slabs. In setting up the wall the slabs are staggeredor arranged in break-joint relation, so that a plate 5 will rest on apartition 7 and in the same course the adjacent partition 7 will rest ona plate 5 as indicated in Fig. 2. In this way vertical columns atregular intervals will be formed and these may be filled with concreteto form studs 9. Between the studs the wall will be hollow and it willbe noted that some of the grooves 3 remain idle.

In forming a corner the slabs are permitted to project in staggeredrelation but set back from the intersection of the outer vertical planesof the wall. A suitable falsework or fonn'is set up and a concretecorner post or column poured. It is obvious that certain deviations maybe made to meet conditions which confront the builder.

In Fig. 4. we have shown a slab 15 which in all respects is the same asthe slab 1 except that it is shorter. The difference in length betweenthe two slabs is made up by a wood block 16 having a vertical groove 17in one edge and a vertical tongue 18 on the other edge. In building awall it is desirable in certain courses to provide means for supportingbase boards, rails, moldings, frames and the like. In such courses theinner tier or plane of the wall may be formed of the short slabs 15 andblocks 16, the grooves 17 receiving the tongues 6 and the tongues 18seating in the grooves 2 of the slab. The blocks will always be disposedagainst the inner sides of the studs which will provide a solidfoundation for nailing.

By making the short slabs and blocks equal in length to the long slabs awall may be quickly and easily built with practically no mathematicalproblems to solve. blocks may be formed of wood or any other materialwhich the builder might decide to use for the purpose. These blocks maybe The placed as desired and may be omitted when not necessary. Theparticular arrangement of the partitions, tie plates and grooves 2 and3, whereby the plates and partitions are disposed in alternate relationvertically of the wall and at the same time in staggered relation withrespect to the studs, is one of the very important features of theinvention and gives to the wall not only a permanency but a properlybonded and substantial construction.

We claim:

1. In a wall construction the combination of a plurality of slabs"superimposed in spaced parallel vertical planes, tie plates interposedand engaging between the ends of the slabs and extending from a coursein one vertical plane to the corresponding course in the other verticalplane, the plates and slabs being locked against lateral displacement,and partitions extending transversely between parallel courses of thewall and having their ends seated in the inner sides of the slabs, saidplates and partitions being disposed in alternate superimposed order andin two transverse vertical planes whereby columns are formed into whichconcrete may be poured to produce studs.

2. In a slab wall construction, a vertical side composed of superimposedvertical slabs, a second vertical side composed of superimposed verticalslabs and spaced from the first side and tied thereto by plates, some ofthe courses of the second side having slabs arranged \in spaced order,and wooden blocks filling in the spaces between the ends of said spacedslabs.

3. In a hollow slab wall construction, superimposed vertical slabsarranged in two vertical planes spaced apart, transverse platesextending from the slabs in one plane to those in the other and engagingbetween the ends of adjacent slabs, some of the slabs being terminatedshort of the plates on one side, and wooden blocks inserted between theextremities of the plates and the ends of the shortened slabs, wherebysaid blocks and plates are locked between the slabs.

In testimony whereof we afiix our signatures.
